|ABOUT THE BIOFOULING CHALLENGE|
In this challenge, Swedish-based Stena Line is seeking solutions to keep a ship’s hull continuously clean of marine organisms (prevent and/or continuously remove biofouling) and can be applied to cargo and passenger ships that travel in all of the world’s oceans.
Biofouling is a natural process that occurs with any structure placed in contact with water where there is the presence of marine micro-organisms. This problem has plagued shipping since the days of the Phoenicians. It begins immediately after the object is placed in the sea, by the adhesion of organic substances and materials dissolved in water, developing in 4-stages with the growth of marine macro-organisms such as algae, barnacles and mussels. Growth of marine organisms is most prolific in warm shallow waters and when at anchor.
The expense relating to fuel in the shipping industry is up to 50% of the total cost of operation for long-haul ocean-going vessels. Studies have shown that marine growth on a heavily bio fouled hull can increase the power requirements by more than 40%, as compared to a newly coated smooth hull.
